x86 seemed most important for now because there was this odd discrepancy 
between 32 and 64 bit (cmpoop did exist before, but only for one special 
case in 32 bit). I will do something similar for aarch64 later (need it 
for Shenandoah). Others will have to fill in the required parts for 
Shenandoah to other platforms, if they need it.

Thanks for all your help!
